Description

Water Inflow Prevention Device for Snorkel {WATER INTAKE PREVENTION DEVICE FOR A SNORKEL}

The present invention generally relates to swimming aids and more particularly to a water inlet prevention device for snorkels.

Snorkeling is a very popular and enjoyable game where divers and swimmers use snorkels to breathe face to face under water. However, in the use of the snorkel the user must maintain a suitable depth just below the surface of the water. If the swimmer descends to a depth beyond the length of the snorkel, water is introduced into the air intake of the snorkel instead of air, which is indispensable for the user. In this case, the sucked water must be blown out with sufficient pressure to drain the water from the snorkel tube and be discharged from the snorkel, thereby allowing the air to be supplied again through the snorkel. Locking down below a suitable depth occurs very frequently, so many devices have been proposed in the prior art to solve this problem.

One such device is Lin, US Patent No. 5,117,817, filed June 2, 1992, entitled "Vertical Coaxial Multi-Tube Diving Snorkel." The invention is characterized by having a float in the outer housing, in which the float rises to block the inlet when the device is underwater.

Christianson's US Patent No. 6,371,108, issued April 16, 2002, "Best Dry Snorkel," suggests another type of float type device. The device has an external float blocking the external inlet.

Hunt's US Pat. No. 4,805,610, registered February 21, 1989, "Snorkel of the swimmer" is another external float device. The device is a device using a ball that blocks the inlet when an external float rises due to the water level.

US Pat. No. 6,513,520 to Vinokur et al., Registered February 4, 2003, uses a snorkel system that is secured around the top of a breathing tube. This design does not use floats, but allows the air inlet path through the housing to act as a pressure chamber to allow the diver to generate sufficient pressure to prevent water from entering the housing.

Despite the many different prior arts above, they have drawbacks to be solved. The ball valve device is too bulky, impedes movement and often fails to completely block the ingress of water. It also impedes movement of the device with the external float, and tends to be caught by various obstacles, such as plants or seaweed, which divers encounter. In addition, other types of devices currently in use use means to prevent the ingress of water, but the means also prevents the ingress of air, making it difficult to breathe even when the snorkel is on the surface.

In order to solve the problems of the prior art as described above, the present invention effectively blocks the inflow of water into the air inlet, even if the inlet of the air inlet is below the water surface to effectively block the inflow of water into the air inlet It is an object to provide a snorkel device.

Another object of the present invention is to provide a snorkel device having a structure that does not interfere with movement and is not easily blocked.

Another object of the present invention is to provide a snorkel device having a structure that is simple to manufacture.

In order to achieve the above object, the present invention relates to a water inflow prevention device for a snorkel (Snorkel), the device includes an outer housing fixed to the air inlet tube of the snorkel. The outer housing includes a plurality of inlets that allow the inflow of air. The inner housing of the device includes a float moving inside the inner housing. When a diver submerges to a depth where the snorkel is submerged, water flows into the air inlet. The introduced water floats the float inside the inner housing so that the tapered top of the float blocks the opening of the air inlet and prevents water from flowing into the air inlet. The inlet of the outer housing should be located below the opening of the air inlet, and should be isolated from the opening of the air inlet, and should be isolated from the air inlet of the snorkel.

When the diver comes close to the water surface, the float is separated from the inner housing air inlet opening so that air flows again through the air inlet of the snorkel. Water that has flowed into the housing flows out through the inlet opening, and the air inlet path of the snorkel is free of water.

The above and other objects and advantages of the present invention are described below and will be apparent to those skilled in the art by the presently best mode techniques for carrying out the present invention, as shown in the figures.

The present invention relates to a water inflow prevention device 10 for the snorkel 12, the water inflow prevention device 10 includes an outer housing 14 and the inner housing (16). The lower portion of the outer housing 14 includes a fastening mechanism 18 for fixing the water inflow prevention device 10 to the air inlet tube 20 of the snorkel 12. Preferably, the fastening mechanism 18 includes two pairs of protrusions that engage with the fastening holes 22 at the top of the air inlet tube 20.

The outer housing 14 includes at least one inlet 24 through which air is introduced. Preferably it may be composed of three pairs of the lower inlet 241 and the upper inlet 242 located around the outer housing 14 at intervals of 120 degrees. The use of the lower and upper inlets 241 and 242 is to keep the snorkel air inlet 20 open as long as possible when the diver descends into the water. In addition, the lower and upper inlets 241 and 242 are not only penetrated into the inner housing 16 but also communicate with the float hole 26 on the upper side of the inner housing 16. The float hole 26 is in communication with at least one air passage 28 defined by an outer housing 14 and an inner housing 16. (See FIG. 4) In order to form the air passage 28, The inner housing 16 must be connected to the outer housing 14 by at least two coupling plates 30. Preferably, the inner housing 16 includes three protruding coupling points (nodes 32), each coupling point (node) 32 is connected to the inner side of the outer housing (14). The configuration forms an air passage 28 which is supplied to the neck portion 34 of the outer housing 14. The neck portion 34 of the outer housing 14 is in turn connected to the top of the air inlet tube 20 of the snorkel 12 to form an air inlet path leading to the diver's mouth. The direction of air flow towards the snorkel 12 is indicated by arrows in FIG. 2.

The inner housing 16 includes a float 36. When water enters the lower inlet 241, the float 36 rises to the top of the inner housing 16 and closes the float hole 26 (see FIG. 3). Preferably the float 36 Has a tapered top 38 so that it is easily guided to the float hole 26. In order to maximize the sealing effect of the tapered top 38, the tapered top may be covered with a rubber cover or the entire float 36 may be made of rubber. The shape of the float 36 may be in various forms (including a simple ball shape) as long as the float 36 can block the float hole 26 when the float 36 rises to the top of the inner housing 16. Float 36 may be used.

The main configuration of the water inflow prevention device 10 of the present invention is that the inlet 24 of the outer housing 14 is more than the float hole 26 of the inner housing 16 defining the air inlet path of the snorkel 12 It is located below and is isolated from the float hole 26.

To help the snorkel 12 maintain its proper posture while the diver is in motion, the snorkel 12 includes a flexible joint 42 and a flotation ring 44. The flexible joint 42 can be made using a fiber or similar form so that no resistance to bending occurs. The flexible joint is installed at a fixed point on the air inlet tube 20 in the snorkel 12. The flotation ring 44 is fixed to the air inlet tube 20 located directly below the water inflow prevention device 10. Any type of flotation material is possible with the material of the flotation ring 44, with a foam disc being a typical example of the flotation ring 44. In the case of having the flexible joint 42 and the support ring 44, the water inflow prevention device 10 preferably maintains the standing state regardless of the diver's body movement with respect to the snorkel 12.

The use of the water inlet prevention device 10 is as follows.

When a diver who is a user floats at a depth at which the water inflow prevention device 10 comes above the water surface, the diver breathes through the mouthpiece 40 of the snorkel. Air enters the inner housing 16 through the upper and lower inlets 241 and 242. The air passes through the float hole 38 through the inner housing 16 and passes through the air passage 28 into the neck of the outer housing 14 inserted into the air inlet tube 20 of the snorkel 12. Flow portion 34. The float 3 is in the open position as shown in FIG. 2.

When the diver is immersed to a depth such that the water inflow prevention device 10 for the snorkel 12 is in the water, water is introduced into the inner housing 16 through the inlets 241 and 242. The water floats the float 36 inside the inner housing 16. When the float 36 reaches the top of the inner housing 16, the tapered top 38 of the float 36 passes through the float hole 38. As the water rises, the float 36 completely blocks the float hole 38 and blocks the air inlet of the snorkel 12 before water enters the air inlet. 3 shows that the float 36 is in the closed position.

As the diver rises and approaches the surface of the water, water flows out of the inner housing 16 through the inlets 241 and 242, and the float 36 moves away from the float hole 38 as the water level drops. do. When the float hole 38 is opened, the air inlet of the snorkel 12 becomes clean again, and the diver can freely breathe through the mouthpiece 40 of the snorkel 12.
